The book´ subject is "forms of the contemporary society", such a "concrete images", that are very hard, almost "promethean", to describe but "in the medium range" (Merton). It can be done through its "shapes", its self-definition and self-reproduction processes that make the (even modest) sociologist, a real "entronaut", to do constant reembedding and conceptual disembedding operations, that appear acrobatically correct and aim to continuously build "the discourse on a discourse", belonging to it and making it meaningful. "Thinking sociologically" (Bauman) mainly means a disciplined look that is methodologically grounded on daily practices, revised in cognitive maps overcoming the immediacy and situatedness of the practice itself and making to talk about "social science" possible.
